OFAKRON, OHIO, ASSIGNOR, BY MESNE ASSLUMMENTS', TO THE PRODUCTS COMPANY, OF AKR-ON, OHIO, A CORPORATION 0F DEMOUNTABLE RIM.

Patented M'ay 24,1921.

Application filed December 9, 1915. Serial No. 65,871.

. a citizen of the United States, residing at Akron, in the county ol" Summit and State of Ohio, have invented certain new and usen ful Ilnprovements in Demountable Rims, of which 'the following' is a specification.

This invention relates to that type ot' 'den'iountahle rim commonly knownas a. split rim7 and particularly to the latch or fastening' means which holds the. ends ot the rim together'and at the same time furmshes a positive connection between the rnn and the wheel, preventing relative movement. It has been the object of this invention to simplify the construction ol the latch as much as possible, in order that it may be madecheaply and in order that the operation ot locking'or collapsing' the rim may be performed easily vand quickly. These and other objects will be apparent trom the fol- I lowing` specifications and the accompanying drawing in which like reference numerals refer to like parts and in which:

Figure 1, is a longitudinal section of the meeting` ends ot the rim on the line'l-l of Fig. 2, showing` the fastening.V means 1n position tor collapse ot the rim.

Fig 2, is a plan view looking` from the inside of the rim showingr the tastening means in closed position.

Fig. 3, is'an isometric view ot the latch.

Fig. 4, is a intalitication ot the turn button. l

The rim shown type known obvious that the .invention is capable of application to rims ot' othertypes'than that shown. The rimis split at`1t), the particular split in this ease being shown as a straight radial split, but the invention is not limited to application to this torni alone as thc splitmay be a diagonalor an irregular split.

(ln the under side'ot the rim, there are .forme-d two inclined ribs 11, which are adapted to be associated with any suitable securine` means for holding' the rim on the wheel. These ribs may he omitted. however, and the nnder side of therim formed smooth.

To one ot' the meeting ends of the rim is [ened a combined latch plate and dowel in 1;. This consists generally ot a tlat in the drawing` is oi'v the at the -latclr asstraight side rim. but it isl end of the rim and tormed with a raised portion '125, the other halt extendingbeyond the rim end and haring an oval shaped slot lLt punched therein. This recess lor hole may take other shapes it desired, but it is believed that thev one shown is the best for the purliose. The portion 13 ot' 'the latch is lnovided with an upstanding dowel 15 which is adapted to seat in a socket in the wheel when the rim is mounted in position forming a connection between the rim and wheel and prevent turning` ot the toriner on the latter. (ln the opposite :tace ot the latch there is formed a projection.' 16 which is adapted to be received in a socket 17 in the end ot the rim, it beine the intention that the end of the projection he riveted into the socket to hold the. latch securely.

On the o]' posite end ot' the rim at a position to be received in the aperture 14, a turn button or pin 1S is mounted for rota# tion in a socket lf). 'The button is enlarged belowthe under surtace ot the rim to .forni a head 2t) in which is a kort' 21 for screw driver operation. ()ne side ot the button is extended over the head to torni a locking surt'ace 22, the under side of which is beveled as in 2P. Thel upper surface ot the button .is in the i'orm ot' an oval which is placed et--ccentricallv with relation to the pivot point ot the button, and w-hen in the position shown in `Fig'. l, the oval head of the vbutton registers with the hole and the rim maybe collapsed, the ovcrl'umgiug edge 22 passing' tree'ly through the slot ll. \\'hen turned to the position as shownin Fig. 2, withthe .ovals out ot register. the wedge surface 23 on the button will ride over the outer edge ot the `slot pullingv the latch into its seat and tormineV a perfect alinement of.

thrim ends. when completel)v turned to the position as shown in Figi. 2,' the latch is irmlv locked and the ends ot' the rim are securelv held together. i

In Fie'. 4. is shown a slight modification ot' the button 21). thel wedge surtace 22 in? stead of terminating at the vertical face of the button is cut ott to Aform a ledge 26. In locking position it will be seen that the flat surface formed on the button engages the under side of the latch and makes amore secure fastening for the rim..

Various other changes and modifications may bel made without :departing from Vthe spirit ot the invention or sacrificing any of its bQiies Within the Scopo of the appended claims.y y i i l. in a demoiuitable split rim, a {astonng device, coinpi'isiug u plato secured to one and of die rim und overlapping the, split zin'd'pi'ovided with a slopq u turn but t0n having :in oveii'iaiiiging portion reizitivey mounted on dio other and of Said rim adapted to through the slot in one p0- Sition and to lock; the rim in. another posi tion, and a Wedge'siufnce on the under Sido ofud o'v'erhiuigiiig portion` Y Q2. `1n :i dmountnble split, rim,` a fastening device comprisingl` d plate secured to one end `of tho'xrim und overlapping the split qnd provided `with L sion a, tiirirbutton having am ovci'hzuigiug portion rotntily mounted on thu other @ml of said rim ndaptedto pass tlnrougrh'the'slot in one position and to lock the rim iii another position, and n Wedge surfzlcc :imi :1, ledge portion on thounder'side of siiix'l` mf'oi'h'uigiiig portion.
